甲基化酶 METTL3 是 RNA N6-甲基腺苷 (m6A) 修饰的写入酶。使用基于结构的药物发现方法,我们鉴定出一种 METTL3 抑制剂,其在生化测定中的效力为 280 nM,而其对映体的活性低 100 倍。我们观察到,在治疗 16  小时后,几个用抑制剂处理的细胞系中 mRNA m6A 甲基化水平出现剂量依赖性降低,这种降低至少持续了 6 天。重要的是,与 METTL3 抑制剂的长时间孵育(长达 6 天)不会改变其他 RNA 修饰(即 m1A、m6Am、m7G)的水平,表明所开发的化合物对其他 RNA 甲基转移酶具有选择性。 Writer's block:我们通过蛋白质晶体学、生化和细胞测定开发并表征了 m6A writer METTL3 的小分子抑制剂。它在生化测定中显示出高纳摩尔效力,对一组蛋白质甲基转移酶和激酶具有良好的选择性,并且降低了不同细胞系 mRNA 中的 m6A/A 比率。此外,我们还证实了我们的化合物对活细胞中其他 RNA 甲基转移酶的选择性。
The methylase METTL3 is the writer enzyme of the N6‐methyladenosine (m6A) modification of RNA. Using a structure‐based drug discovery approach, we identified a METTL3 inhibitor with potency in a biochemical assay of 280 nM, while its enantiomer is 100 times less active. We observed a dose‐dependent reduction in the m6A methylation level of mRNA in several cell lines treated with the inhibitor already after 16 h of treatment, which lasted for at least 6 days. Importantly, the prolonged incubation (up to 6 days) with the METTL3 inhibitor did not alter levels of other RNA modifications (i. e., m1A, m6Am, m7G), suggesting selectivity of the developed compound towards other RNA methyltransferases. Writer's block: We developed and characterized a small‐molecule inhibitor of m6A writer METTL3 by protein crystallography, biochemical and cellular assays. It shows high‐nanomolar potency in the biochemical assay, good selectivity against a panel of protein methyltransferases and kinases, and it reduced m6A/A ratio in mRNAs of different cell lines. In addition, we confirmed the selectivity of our compound towards other RNA methyltransferases in living cells.
